SuperiorQuality
– Unique Advantages…
The freeze drying technology simply gives you the highest quality in the market. Frozen products are dried under vacuum, ensuring that the inherent solvents in the product (i.e. water) are removed as vapour. This preserves the overall product structure and size, as well as all nutrients, flavours, and colours.
In our LomSyst ™ freeze
dryers, frozen products
are dried at temperatures
below –18° C.
No thawing of the
product takes place and
its quality is preserved.
Meeting market demands Today, customers request food that is easy to prepare and keeps well without being spoiled while retaining the characteristics of fresh food. Freeze drying allows manufacturers to meet these demands by preserving the natural look and consistency of the product as well as all its flavours, proteins, and vitamins.
Unique advantages As one of the most experienced designers and manufacturers of freeze drying plants in the world,LomSyst combines unique technology with reliable plant operation. While providing the superior product quality you need in order to stay ahead of your competitors, our LomSystem™
technology gives you unique economical and technical advantages:
• The freeze drying process results in stable products with a long shelf life. • Freeze dried products are durable at a wide range of temperatures, eliminating the need for complicated cold chain distribution systems. • The low weight and easy handling of freeze dried products reduce shipping costs dramatically. On top of that, LomSystem™ freeze drying plants are designed to: • Eliminate product loss • Reduce energy costs • Maximise plant reliability and ease of use.

Refined Efficiency We have refined the freeze drying
process to a point where we are able to
supply the most efficient and economical
freeze drying plant designs in the
market. The advantages of selecting our
equipment include:
Modular Design The LomSystem™ freeze dryers from
LomSystem are designed as modular
systems, with cabinet, heating plates,
and vapour condensers built as
individual units.
The modular design offers a number
of advantages during installation and
operation:
• Shorter interval between order and
commercial production thanks to quick
installation.
• Local subcontracting becomes a
viable option for dryer assembly.
• Easy access for cleaning
and maintenance.

LomSyst™ A water-flushing de-icing system is used for
the smaller LomSyst™ (2, 8, 16, 30, 45) cabinets.
At the end of every freeze drying cycle, the
condenser is flushed with pre-heated water.
Ice in the condenser melts within 10 minutes,
whereupon the water is drained. This method
is ideal for smaller systems, ensuring:
• Minimum investment cost.
• Simple operation.
LomSyst™ with CDI The larger LomSystem™ (50,75, 100, 125, 150) cabinets
incorporate the Continuous De-Icing System
(CDI). During de-icing, vapour at 25° C from
the de-icing vessel condenses on the cold
condenser surface, thus melting the ice. In order
to restore the condenser to operating condition,
the condenser chamber is closed off from the
de-icing vessel. The condenser is cooled to
operating temperature, resulting in the
condensation of any remaining vapour.
As the vapour condenses, the pressure in the
condenser decreases until operating vacuum is
achieved eliminating any loss of operating
vacuum at switch-over between vapour
condenser chambers.
The CDI system is fully automatic. It ensures:
• An ice layer on the condenser coils of max.
5 mm (1/5”), resulting in a negligible
temperature drop over the ice and low
energy consumption in the refrigeration
plant.
• Constant condenser capacity.
• High freeze drying capacity per square
metre of tray surface.
• Short time from one charge to another.
• Higher overall profitability in your
large-scale freeze drying process.
Advanced Simplicity:
Complete Plants with the Europe Concept
Advanced simplicity is the best way
to describe the LomSystem™
concept from Europe
As part of the Process Engineering
Division of the Sainty Group, LomSyst
offers a full range of plant services
worldwide – from turnkey solutions
to that vital piece of equipment that
will make your freeze drying process
profitable.
Service Beyond Delivery In addition to actual plant delivery,
LomSyst has the experience and
market know-how to support you
in your product research and
feasibility studies.
The LomSyst™ concept is the result of many years of plant and process
development based on research and
collaboration with our customers in
all parts of the world. The result is a
freeze drying process – as shown in
the diagram – that is second to none.
The Full Range The LomSyst™ plant is capable
of handling most freeze drying operations.
LomSyst™ 125 plant for vegetable,
1 LomSyst™ 8 plant for various products/test
2 LomSyst™ 125-S plants for sanitary applications.
Monitor the entire process on-site or from a central control room.
4 Heat supply system Drying is carefully controlled
throughout the temperature range
– from below freezing temperature
(brine) or room temperature (cooling
water) up to 130°C – to ensure perfect
product quality.
5 Vacuum system Process vacuum is typically achieved in
less than 10-12 minutes depending on
RAY™ type.
If you have products with special
requirements, this time can be reduced. .6 De-Icing
Type CDI
1 Tunnel freezing/frost storage One 8-hour preparation shift provides
sufficient product for 24 hours of
freeze drying. Freezing is by the “first
in/first out” principle.
2 Transport by overhead rail Trolleys carry the product trays from
freezing, through freeze drying, to
emptying. A simple, hygienic, and safe
system.
3 LomSyst™ freeze dryer Fully automatic control of the drying
cycle for each batch. Just close the
door and press the button
From engineering and construction the entire process.
7 Refrigeration system Incorporates highly efficient
refrigeration compressors with
automatic capacity control.
8 PC/PLC control system The control system ensures optimal
operating conditions throughout the
plant – freezing, drying and
associated heating, vacuum and
refrigeration systems. Remote control
